checked the date of the indi drivers in /usr:
indiserver and skywatcherAltAzMount are with date of today. indi_eqmod_telescope is Apr 13.
Tried to "handconnect", also. No success.

I updated the driver, you can refresh your clone:
cd ~/Projects/indi
git pull
and rebuild/reinstall. And retry. Beware of USB extension cable, I also had connection issues while testing, just reconnect them and that was ok.

did the update. AltAzSimple still handshake failing; skywatcherAltAz does not connect due to other reasons. Log attached. First attempt is with AltAzSimple (because there the connection at least was initiated), second with skywatcher_AltAZ

Dear Jasem, sorry to be communicating about the same subject on many fronts (Stellarmate support ticket HAYB-000932, Github enhancement demand github.com/indilib/indi/issues/1232, and now here).
As I mentioned in both other places, the version of the indi_skywatcherAltAzMount driver you are using with the alias AZ-GTI AltAz is the one that still contains the bug that doesn't allow UDP connection with Az-GTI, as explained -and then solved- in this GitHub bug github.com/indilib/indi/issues/1158).
So that's the first problem. The second problem for is that when using AZ-GTI in AltAz with indi_skywatcherAltAzMount driver (not your version), it does not track. The driver connects through WiFi (UDP), and then it is parked. If I unpark, it goes somewhere, but when it gets there it doesn't track. I can slew somewhere else (sometimes, sometimes it stops) but again when it gets to destination it does not track.
As the original post demanded, I also think the best would be to have an AltAz "translation layer" between Ekos and AZ-GTI eqmod-based driver, translating from AltAz to EQ and back in every interaction with said driver, would that be possible? Since that driver works seamlessly with AZ-GTI whereas the indi_skywatcherAltAzMount driver does not.

It's alright! Ok, let's move all the discussions here :D

I am using this driver with my AZ-GTi Alt-Az driver over UDP.



I just tested this and issued GOTO to Phecda. It slewed there and it was tracking. RA/DE are constant while AZ/AL change to keep the object centered.



I'm not sure I follow the last point though.. you want to help explicit Az/Alt input in the driver? This can be added, but it's not strictly necessary. If this is required for a very good reason, then I'll add it. Otherwise usually clients simply send the RA/DE and the driver internally converts that to Al/Az and command the mount.

Ok, I see that you are making it work.
In my case, after switching to the beta channel, only one driver works (AZ-GTI AltAz), all other drivers (including Nikon, etc) give me the "driver xxxx was not found on the system" error (and then Kstars closes). So that's bad, I think I'll have to download the image and start all over again. It's frustrating because I had downloaded the 4+ gb plate solving data files and my connection is slow.

In any case, the AZ-GTI AltAz driver (which does work) does not connect via UDP. I don't know why. The indi-SkyWatcher-AltAzMount driver did connect fine via UDP, but did not track correctly.

My last point was about what I mentioned in github.com/indilib/indi/issues/1232 enhancement: the point is that AZ-GTI driver is a superior driver compared to indi_Skywatcher_AltAzMount in many ways, it has more features and is more stable I think. If I am correct, then my point is that it would be better to make an AltAz version of that driver, an altAz version of the Eqmod driver beneath it. I know that sounds difficult, but that way altaz users would inherit all the advantages of the AZ-GTI driver and you would have a unified driver for altaz/EQ use, I think.

No need to reflash again. Make sure to update_indi_core and update_indi_drivers then remove the Ekos profile and recreate it again. Hopefully that should help you run all the devices. If not, we can try Teamviewer method again.

Dear Jasem, yesterday night I switched back to the Stable Stellarmate channel and after the switch all works, including UDP with AZ-GTI AltAz driver you made.
Unfortunately, as I mentioned, the driver it is based on (indi_skywatcher_altazmount) has bugs.
The first one is that, when tracking, in the Mount section the tracking button is not set to ON (both ON and OFF are greyed out).
The second, more important problem is that when tracking an object, Jupiter for instance, the mount will, every few seconds, slew on its own randomly, for example slew up a little bit, or slew left a little bit, then begin tracking again, then slew again...
When using the Alignment module, plate solving will be interrupted very often with the message "slewing detected aborting solving".
I tried by disabling the SoftPEC option, but crazy slewing continued.
I'm sure this can be solved. I'm also still inclined to think having two different AZ-GTI drivers, one based on indi_skywatcher_altazmount and the other on eqmod might not be the best road, and that it might be better to modify the eqmod based driver to work with altaz instead.

I hope Jean-Luc's driver would work with AZ-GTi so it's a win-win on all fronts. I just attempted to use an existing driver that was tailored to Alt-Az mounts but it wasn't tested good enough I suppose. Let's wait to see when EQMod Alt/Az modifications take place.

Dear Jean-Luc, as I mentioned in my recent exchange with Jasem, both skywatcherAltAzSimple and indi_Skywatcher_AltAzMount drivers are buggy on many front; particularly, with the AZ-GTI mount, the mount keeps slewing randomly for no reason, these are small slews but enough to slip from your target. When you try to do platesolve-alignment, alignment is continuously stopped by an error that says "slewing detected, aborting solving". Also, it's difficult to provide any stable piture of stars for plate solving because tracking is significantly bad. These two drivers, at least when connected through UDP with the AZ-GTI mount, give very bad results in my experience. Compare that with your driver, based on eqmod: I've been using it (in EQ) for months, never a bug, tracking is perfect, etc etc. So I believe strongly that the best would be to have an option in your driver for alt-az mounts. That would also alt-az users to profit from all future features added to your driver. For instance, recently a version of your driver added a feature to use the SNAP port of the AZ-GTI mount to take pictures longer than 30s with DSLRs (github.com/indilib/indi/issues/1181) - although pictures longer than 30s are not probably a good idea for altaz operation, it would be nice to have the feature to try. Thank you so much for your work on this driver!!!
